Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed May 10, 1905. Serial No. 259,670.

To ZML w/wm it may concern:

Be it known that 1, JOHN I. MAGUIRE, a citizen of the United States,residing at Wayne, in the county of Delaware and State of Pennsylvania,have invented certain new and useful Improvements in Wheels, of whichthe following is a specification.

My invention has relation to improvements in wheels for vehicles, and insuch connection it relates to the general construction and arrangementof such wheels.

Hitherto wheels have been designed solid to be driven either by an axleor other means when the wheels were mounted loosely on the axle orshaft. Such wheels when employed on automobiles as rear or drivingWheels required special mechanism to permit the wheels driven with equalspeed to turn with unequal speed in passing round corners or in themovement of the vehicles in curves to overcome so-called skidding or ofthe turning of one of the wheels, which in such movements describes ormoves in a smaller curve. Furthermore, in instances where the motor ofsuch a vehicle becomes unmanageable and incapable of being stopped thewheels positively driven by the motor could not be prevented fromrotation by the application of a brake without destruction of the same.Neither could the wheels in the case of an accident be suddenly stoppedby the brake without causing overturning of the vehicle.

The principal. objects of my invention are therefore to overcome theabove-mentioned disadvantages and to provide a wheel formed ofdisconnected sections concentrically arranged with respect to eachother, which under normal conditions permit the driving of the wheel byengaging and positively turning one of its sections, while underabnormal conditions permit the free turning of one section within theother.

The nature and characteristic features of my invention will be morefully understood from the following description, taken in connectionwith the accompanying drawings, forming part hereof, in which Figure 1-is a side elevational view of a Wheel embodying main features of myinvention having a certain portion thereof broken away, and Fig. 2 is across-sectional view thereof.

Referrmg to the drawings, A represents a wheel conslsting of twosections a and 0 abutting directly against each other, with the hubextension 0 of the inner section 0 provided with bolts 0 loosely mountedtherein, the threaded ends of which engage blocks 0*, bearing againstthe ring a of the outer section a. By the turning of the bolts 0 thefrictional engagement of the blocks 0 with the ring a can be regulatedaccording to the load the Wheel is normally adapted to carry and also totake up the wear between the blocks 0* and the ring (4 After the bolts 0have been turned the same are held in the position given by the jam-nuts0 bearing against the blocks o as shown in Fig. 2. In this wheel thespokes are dispensed with and are replaced by disks 0 and a", secured,respectively, to the rim (0 of the section a and the ring In order toform a' channel-way and to permit free removal and reinsertion of theblocks 0 into the channel-way, the disk (0 is extended beyond the ring aand a removable ring a provided, which forms an extension of the disk aas shown in Fig. 2.

Having thus described the nature and objects of my invention, what I'claim as new, and desire to secure by Letters Patent, is.

1. A wheel, consisting of inner and outer sections abutting directlyagainst each other, the inner section being provided with a hubextension having bolts, the threaded ends of which bolts engage blocksbearing against a ring of said outer section, disks detachably connectedwith the rim and ring of said outer section,'a channel-way to permit theremoval and insertion of said blocks, one of said disks being extendedbeyond said ring and a removable ring to form an extension of said disk.
